Look at the USDZ Specifications for information for most of the data. The problem there is that there is data carried in the file the is proprietary to Apple and only the Apple sanctioned apps seem to be able to process it. Am I correct?

That would be in the Room Plan sample, sorry

Now I am hitting the lack of a "View Controller" Entry point because there is not a view controller in the file set for this application I wonder why two key elements would e missing from the sample application code files for this demo package. The application sample as released is not ready for prime time yett an how much more of my time will be spent running into issues like this? There is nothing in the readme file that indicates we should expect such stumbling blocks

Franklan I finally got mine to work. I went into XCODE and Under the Files/NEW Tab created a NEW dummy Storyboard file called "MAIN" which after rebuilding my app it worked. The results were startling but I got something that showed progress. Good Luck when you try it

I had a similar problem with the Sample code. It builds just fine but when loaded on the iPad to test it fails because the demo did not include the Storyboard files for the Main Window. In Fact, there are no storyboard files included at all in the zip file used for the demo.and this is not the first time this happened with a sample. How are we to execute a demo programme that is lacking major components of its environment? It's not like the demo was put out there yesterday. I am surprised nobody checked their work with the actual distribution copy of the demo sample.
